| Accurate stellar radial velocities measured from high-resolution spectrographs constitue a powerful technique to study exoplanetary systems. That indirect method allowed the first exoplanets to be detected and continues providing numerous results. The SOPHIE environmentally stabilized echelle spectrograph at Haute-Provence Observatory 1.93-m telescope, France, is widely used for such studies. SOPHIE is employed to perform radial velocity surveys in different stellar samples, and for the follow-up of space- and ground-based photometric surveys for transiting planets. Those programs yield new detections and characterizations in an increasing parameters space. They also provide statistics on the planetary populations. I will present the SOPHIE instrument and programs, and review some of their results in exoplanetary science. |
